Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
bfd_count top_index, input_list, all_local_syms.
(elf32_hppa_setup_section_lists): New function, split from
elf32_hppa_size_stubs.
(elf32_hppa_next_input_section): Likewise.
(group_sections): Likewise.
(get_local_syms): Likewise.
(elf32_hppa_size_stubs): Adjust for split out functions. Look for
stubs on undefined syms too.
(elf32_hppa_set_gp): Use bfd_link_hash* instead of elf_link_hash*.
Only access htab elf fields when we have and elf hash table.
